What is trabecular rarefaction?
A pseudocyst is a normal variant that looks like a lytic lesion but is actually a rarefaction of the normal trabecular pattern; the trabecular rarefaction is a low stress area of bone that becomes apparent when it is surrounded by more prominent higher stress areas.
What is bone rarefaction?
oxford. views 1,428,169 updated. rarefaction (rair-i-fak-shŏn) n. thinning of bony tissue sufficient to cause decreased density of bone to X-rays, as in osteoporosis.
What is the trabecular bone?
Introduction. Trabecular bone tissue is a hierarchical, spongy, and porous material composed of hard and soft tissue components which can be found at the epiphyses and metaphyses of long bones and in the vertebral bodies (Fig.
What is the difference between cortical and trabecular bone?
Cortical, or compact, bone is found mainly in the shafts of long bones and accounts for roughly 80% of bone mass [1]. Trabecular bone is found in vertebrae and the ends of long bones and is, in contrast, a porous foam-like structure with voids filled with bone marrow.
What is the treatment for lytic lesion?
Lytic lesions in the long bones of the leg or in the hip may require surgery to reinforce and stabilize the bone.
Can lytic bone lesions be benign?
They are benign, asymptomatic tumors with a well-defined sclerotic margin. They are usually juxtacortical in location and typically occur in the metaphysis of long bones, and are most common in the under 30 age group.
What is rarefaction in science definition?
rarefaction, in the physics of sound, segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression. A succession of rarefactions and compressions makes up the longitudinal wave motion that emanates from an acoustic source.
What causes bone rarefaction?
Osteoporosis is a systemic bone, and autoimmune disease. It is characterised by a reduction in bone mass and an alteration of the microarchitecture of bone tissue. This disease generates a progressive bone rarefaction and bone demineralisation, also called decalcification.
What is trabeculae in botany?
trabecula. / (trəˈbɛkjʊlə) / noun plural -lae (-ˌliː) anatomy botany. any of various rod-shaped structures that divide organs into separate chambers. any of various rod-shaped cells or structures that bridge a cavity, as within the capsule of a moss or across the lumen of a cell.
What is a trabecular pattern?
Trabecula is a supportive and connective tissue element which form in cancellous bone. Trabeculae develop in a normal bone and also in a healing bone. The trabecular pattern of growth follows the course of stress lines along the bone and maximum trabeculae develop along the lines of maximum stress.
What does trabecular mean?
1 : a small bar, rod, bundle of fibers, or septal membrane in the framework of a body organ or part. 2 : a fold, ridge, or bar projecting into or extending from a plant part especially : a row of cells bridging an intercellular space.
